Abstract
The invention provides a poultice or sacrificial render comprising fibrous material and diatomaceous earth. Preferably, the ratio of fiber to diatomaceous earth is in the range 1:6 to 6:1 and the fibrous material contains relatively long fibers, such as would be obtained from the manufacturing or pulping of quality paper, for example fibers in the range 1 mm to 4 mm. The invention also provides a poultice mixture comprising fiber, diatomaceous earth and water and optional additives such as a binder or thickening agent and a biocide. The invention also provides a method of removing salt from a salt permeable object comprising the step of applying the poultice mixture to the salt permeable object.
Claims23
A material for forming a poultice or sacrificial render, comprising:
- a fluid permeable substrate comprising cellulose fibres;
- and
- an agent for increasing the internal surface area of the poultice or sacrificial render relative to the substrate alone, said agent comprising an agent selected from diatomaceous earth or perlite.
A mixture or forming a poultice or sacrificial render, comprising:
- a fluid permeable substrate comprising cellulose fibres;
- an agent for increasing the internal surface area of the poultice or sacrificial render relative to the substrate alone, said agent comprising an agent selected from diatomaceous earth or perlite;
- and
- water.
A material for forming a poultice or sacrificial render, comprising:
- cellulose fibres;
- an agent including at least one of diatomaceous earth and perlite;
- a cellulose thickener;
- and
- a pH adjusting substance including calcium carbonate,
- wherein the ratio of the cellulose to the agent is at least 1:1, the ratio of the cellulose and agent to the thickener is at least 125:0.3, and the ratio of the cellulose and agent to the pH adjusting substance is at least 125:0.375.
